Abstract
Valuable metals in manganese nodules have their solvent solubilities altered by forming an alkaline-manganese electric cell using manganese nodules as a cathode active material component and discharging the cell with a selected discharge load. Thus, the solvent extraction percentage for Mn in manganese nodules can be controlled to less than 60% and that for other valuable metals be elevated to at least 80% by selecting the discharge load properly.
Claims5
A process for treating manganese nodules which comprises forming an alkaline-manganese electric cell using the manganese nodules as a cathode active material component and an amalgamated Zn powder as an anode active material component and discharging said cell with a selected discharge load to thereby alter the solvent solubility of valuable metals in the manganese nodules.
